Professor Ned Brainard (Fred MacMurray) needs money for Medfield College. The Pentagon has made flubber top secret. He's running into red tape over the payment. The IRS is after him despite not receiving any actual money. Mr. Hawk is eager to see him fail. The college needs $350k by the first of the month to pay Hawk back. Ned's solution is to invent weather controlling flubbergas. Betsy's not impressed. Despite his objection, Betsy invites Shelby. To Betsy's horror, Shelby invites Ned's old flame Desiree de la Roche/Mary Lee Spooner.

Hawk is a solid villain. The IRS guy is more annoying than funny. Then the money issue gets overused. I have a problem with Betsy. She's made out to be a flighty jealous money-grubber. The movie still has the wacky invention and the socially tone-deaf professor but his dismissal of her isn't that nice either. Their relationship is problematic and seems to be built on rickety scaffolding. It's meant to be funny like a sitcom. The movie really needs to start the couple with love before it injects all the obstacles. That really turns me off.

Proving that the Disney studios didn't become cash-mongers solely in the Michael Eisner era, this sequel to 1961's "The Absent Minded Professor" is nothing more than repackaged goods. Lamebrained slapstick has Fred MacMurray returning to role of small town inventor who attempts to save the local high school from ruin. There are a few funny digs at the advertising business but, as with the original, MacMurray's romance problems and his run-ins with the law are dull. Terrific supporting cast (Jack Albertson, Joanna Moore, Paul Lynde, William Demarest) looks like a who's-who of suburban comedies, and the movie is fairly easy to sit through if you don't mind completely innocuous fare, but even the special effects are mechanical. ** from ****

this sequel to The Absent Minded Professor is actually a better movie.i found it funnier,more entertaining and it had a better story.the character were expanded a bit more,which makes sense,since it is a sequel.unlike Professor,this one doesn't have any slow or boring moments.it's much better paced.i like the fact that the wife had more to do in this one.the movie is just as silly,but it's meant to be,and if you keep that in mind going in,you'll probably enjoy it more.it's not high art or anything,but it will keep you entertained for 102 minutes or so.and it's fun for the whole family.my vote for The Son of Flubber:6.5/10
